OK guys I'm looking for a how-to just bought a 1968 GTX that's got manual steering and I would like to put power steering on it what do I need and where can I get it?

I sell the Borgeson boxes along with the couplers and fittings I manufacture. I can also supply the pump, brackets, pulleys, etc. Bergmanautocraft.com

Bergman sells a complete package that is perfect fro your situation. Just make sure you read up on the threads on this forum about proper alignment and "break in" of the box on installation, and you'll have a blast!

What is the cost for a complete conversion?

Can you tell me more about this "break in"?

We had a couple of boxes and there have been a couple of folks here on the forum that have had issues with the splining on the output shaft not properly engaging the pitman arm. We've had to retorque a few of them as they settle in, and each time we torque them, we get more threads visible (same threads where folks aren't getting full thread engagement on the nuts after installation). After 2 or 3 rechecks, they seems to hold well. Not a big deal for folks that do periodic inspections, but the fire and forget crowd could have a problem.
